TOOL-CARRIER FOR STONE-DRESSING MACHINES.

Original application filed February 20, 1912, Serial No. 678,781.

November 23, 1912.

To all whom 2'15 may concern:

Be it known that I, WILBER H. VAN SIoxnL, a citizen of the United States, residing at Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented a new and useful Improvement in Tool-Carriers for Stone-Dressing Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, which form a part of this specification.

The object of my invention is to provide a new and improved tool carrier of that type which is adapted to be moved back and forth on a horizontally extending frame or arm which is supported on an upright or standard mounted on a portable base and which is adjustable vertically upon its sup port so as to vary the distance of the tool above the ground level, and also revoluble upon its support, whereby the tool is adapted to be brought into pro-per relation to the work to be done wherever, within a fixed area, the latter may be located. Such carriers are known in the art and for an ex ample thereof, I refer to the patent issued to me October 4, 1910, No. 971,577.

In the drawings, which illustrate a preferred embodiment of my invention: Figure 1 is a side elevation partly broken away of the tool carrier and the arm on which it is mounted; Fig. 2 is an end elevation, partly in section, of the same.

I have not illustrated the means for sup porting the frame upon which the carrier travels nor the means whereby the frame is adjustable vertically and revolubly, as these features of construction form no part of my invention.

The toolcarrying frame comprises two parallel arms 9, g. The tool carrier is provided with two pairs of wheels 9. The wheels of a pair travel on the tops of the respective arms 9. The tool carrier consists of a yoke 8 extending between and below the arms 9 and having side guiding surfaces adapted to the inside faces of the arms and guiding pieces 1' extending beneath and adapted to the lower edges of Specification of Letters Patent.

the arms. The yoke is mounted on the axles 25 upon which the wheels 9 revolve. The orifices a in the yoke surrounding the axles are eccentric to the axles, and the yoke is secured to the axles by the set screws '2). By this arrangement the guiding pieces r may be maintained in proper relation to the under surface of the arms 9. If any wear takes place the set screws of either or both axles may be released and the axle or axles turned until the proper guiding contact is obtained. Either axle may readily be turned by means of a rod or bar inserted into the orifice w in the axle.

The subject matter herein set forth and claimed has been divided out of an application filed by me February 20, 1912, Serial No. 678,781.

Having now fully described my invention, what I claim and desire to protect by Letters Patent is:

1. Tool carrying means comprising a pair of arms spaced apart, two pairs of wheels, axles on which the wheels are mounted, the wheels adapted to travel on the arms, a tool carrier comprising a yoke whose opposite arms each extend between the wheels of a pair, said arms being sleeved on the axles, the part of each axle upon which a wheel is mounted being eccentric to the part of the axle on which the yoke is sleeved, said yoke having outwardly projecting guiding parts provided with guiding surfaces adapted to the inside faces of the arms and outwardly projecting guiding parts adapted to the lower edges of the arms, and means to adjustably secure the axles in the positions to which they are turned.

2. Tool carrying means comprising apair of arms spaced apart, two pairs of wheels, axles on which the wheels are mounted, the wheels adapted to travel on the arms, a tool carrier comprising a yoke whose opposite arms each extend between the wheels of a pair, said arms being sleeved on the axles, the part of each axle upon which the yoke is sleeved having an encircling groove and being eccentric to the part of the axle on which a wheel is mounted, and a set screw carried by the yoke arms and engaging said hereunto set my hand, at Philadelphia, on

groove, said yoke having outwardly projectthis 14th day of November, 1912.
